Payouts for end of liability balance

Hi everyone,
after several years of inactivity I checked my Prohashing balance which shows several coins with "This balance is over 90 days old witout any earnings or payouts, making it subject to prohashings "end of liability" policy.

I can understand that the liability disappears due to inactivity but how can I get a payout for those now that I dont mine with my previous setup anymore ?

Thanks and regards

K
